My friend crops his pit bulls ears, because the floppy ears make them look ''sissy''. But personally though I think they look better with the floppy ears, and they look like cats to me when they have their ears crop. Whats your opinion on cropped ears on a pit vs natural ears?

I'm a fan of natural ears.
I never understood cropped ears on pit bulls, not that I'm against them, but you can read a LOT of a pit bulls emotions in his/her ears.
With pit bulls, if the owner crops the ears, they have to be careful to find a vet that does them REAL GOOD, or else the crop job can look REALLY bad.
